From the action bar documentation:
"It's important that you always define android:title for each menu item
— even if you don't declare that the title appear with the action item —
for three reasons:

* If there's not enough room in the action bar for the action item, the
  menu item appears in the overflow menu and only the title appears.
* Screen readers for sight-impaired users read the menu item's title.
* If the action item appears with only the icon, a user can long-press
  the item to reveal a tool-tip that displays the action item's
  title.

The android:icon is always optional, but recommended.

!!! Tip
   This lint check has an associated quickfix available in the IDE.

(##) Example

Here is an example of lint warnings produced by this check:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text
res/menu/titles.xml:3:Error: Menu items should specify a title
[MenuTitle]
    &lt;item android:id="@+id/action_bar_progress_spinner"
     ----
res/menu/titles.xml:12:Error: Menu items should specify a title
[MenuTitle]
    &lt;item android:id="@+id/menu_plus_one"
     ----
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here is the source file referenced above:

`res/menu/titles.xml`:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~xml linenumbers
&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
    &lt;item android:id="@+id/action_bar_progress_spinner"
        android:showAsAction="always"
        android:background="@null"
        android:selectableItemBackground="@null"
        android:actionLayout="@layout/action_bar_progress_spinner_layout"/&gt;
    &lt;item android:id="@+id/refresh"
        android:title="@string/menu_refresh"
        android:showAsAction="always"
        android:icon="@drawable/ic_menu_refresh"/&gt;
    &lt;item android:id="@+id/menu_plus_one"
        android:showAsAction="always"
        android:icon="@drawable/ic_menu_plus1"/&gt;
&lt;/menu&gt;

for the unit tests for this check to see additional scenarios.

The above example was automatically extracted from the first unit test
found for this lint check, `TitleDetector.testBasic`.

(##) Suppressing

You can suppress false positives using one of the following mechanisms:

* Adding the suppression attribute `tools:ignore="MenuTitle"` on the
  problematic XML element (or one of its enclosing elements). You may
  also need to add the following namespace declaration on the root
  element in the XML file if it's not already there:
  `xmlns:tools="http://schemas.android.com/tools"`.

  ```xml
  &lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;item xmlns:tools="http://schemas.android.com/tools"
      tools:ignore="MenuTitle" ...&gt;
    ...
  &lt;/item&gt;
  ```

* Using a special `lint.xml` file in the source tree which turns off
  the check in that folder and any sub folder. A simple file might look
  like this:
  ```xml
  &lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;lint&gt;
      &lt;issue id="MenuTitle" severity="ignore" /&gt;
  &lt;/lint&gt;
  ```
  Instead of `ignore` you can also change the severity here, for
  example from `error` to `warning`. You can find additional
  documentation on how to filter issues by path, regular expression and
  so on
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html).

* In Gradle projects, using the DSL syntax to configure lint. For
  example, you can use something like
  ```gradle
  lintOptions {
      disable 'MenuTitle'
  }
  ```
  In Android projects this should be nested inside an `android { }`
  block.

* For manual invocations of `lint`, using the `--ignore` flag:
  ```
  $ lint --ignore MenuTitle ...`
  ```

* Last, but not least, using baselines, as discussed
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
